86 The Temporal Plot Tool is a wxGUI component that queries and plots the
87 values of a point, defined by a coordinate pair, in one or more tempo‐
88 ral datasets (strds, stvds, str3ds).
89 Supported features:
91 • temporal datasets with interval/point and absolute/relative
93 time,
94 • show simple linear regression model line with calculated for‐
96 mula
97 y = a + b*x (y is dependent variable, a is intercept, b is slope, x is explanatory variable)
98 and
99 r-squared (parameter of goodness-of-fit measure for linear regression model)
100 • pop-up annotations with values information,
102 • query and plot multiple points via the command line,
104 • zoom and pan,
106 • change labels to x and y axes,
108 • add title to the plot, and
110 • export the time series values to a CSV file (x axis data has
112 date time string format, if you want to use for calculating
113 simple regression model in the R environment, LibreOffice etc.,
114 you will obtain a different calculated formula
115 y = a + b*x
116 because these software packages use a reference date other than
117 the UNIX Epoch time (00:00:00 UTC on 1 January 1970)).
118 Figure: Temporal Plot Tool To optionally add a title to the temporal
119 plot and/or change the x and y axes labels, first type the desired text
120 and then click Draw as showed below.
121 Figure: Add title and labels to a time series plot To export the time
122 series data to a text file (date and data values), type a name for the
123 file and click Draw again. Optionally, set the check-box to print head‐
124 ers, as well.
